Cardiovascular and Ocular Parameter Alterations in Response to Cold Pressor Test in Young Adults.

The sympathetic nervous responses to cold stress are known; however, concurrent cardiovascular and ocular parameter alterations in the responses are poorly characterized. The aim of this study was to examine the influence of the cold pressor test (CPT) on cardiovascular and ocular parameters in young adult subjects. There was a total of 86 participants.

Hypobaric type oxygenators - physics and physiology.

Brain injury is still a serious complication after cardiac surgery. Gaseous microemboli (GME) are known to contribute to both short and longer-term brain injury after cardiac surgery. Hypobaric and novel dual-chamber oxygenators use the physical behaviors and properties of gases to reduce GME.

Cold Pressor Test Influences the Cardio-Ankle Vascular Index in Healthy Overweight Young Adults.

Objective: The cold pressor test (CPT) has been shown a potential sympathoexcitatory stimulus which increases aortic pulse wave velocity and the aortic augmentation index, suggesting that noninvasively, arterial stiffness parameters are altered by the CPT. The cardio-ankle vascular index (CAVI) is widely used for reflecting arterial stiffness, and the ankle-brachial index (ABI) for evaluating peripheral artery disease in obesity. We aimed to assess CAVI and ABI in overweight young adults in the context of sympathetic activation by using the CPT.

Correlation between body mass index and ocular parameters.

To investigate the relationship between BMI and selected ocular parameters. Fifty-three left eyes of normal weight subjects and 67 age-sex matched overweight subjects were studied. Inclusion criteria for the normal weight and overweight groups included BMI between 18.

Correlation between cardio-ankle vascular index and biomarkers of oxidative stress.

Arterial stiffness is a pathological event related to arteriosclerosis that is also closely related to oxidative stress. The cardio-ankle vascular index (CAVI) is a novel arteriosclerotic index that has been used to detect arterial stiffness. However, the association between CAVI and oxidative stress has not yet been elucidated, especially in patients with risk of metabolic disorders.
